Which of the following actions does NOT help reduce the spread of disease?

Using white service towels does not inherently contribute to reducing the spread of disease because the color of the towels does not influence their cleanliness or effectiveness in sanitation. While using white towels may help in visually identifying stains or dirt to ensure that they are replaced when soiled, the primary factor in preventing disease transmission is the proper cleaning and sanitizing of towels, regardless of their color.

In contrast, wearing disposable gloves, disposing of single-use items, and regularly cleaning surfaces directly contribute to minimizing the risk of infection by creating barriers between pathogens and individuals, removing contaminants from the environment, and ensuring that surfaces do not harbor infectious agents. It's essential to follow proper sanitation protocols to ensure a safe environment in any cosmetology practice.
